in ubuntu there are two users created klein,beth
i have done as i always do:

sudo smbpasswd -a klein

i'm on a local network at home and i use the same passwd for samba as
well as my ubuntu login

everything works as expected the problem comes when i try to add beth to samba first i did:
sudo smbpasswd -a beth
my passwd
her passwd
her passwd

sudo smbpasswd -e beth
my passwd
beth added

then i added her to the valid user:
valid users = beth, klein

after rebooting from another ubuntu 10.04 computer i can browse to places > network > t5026 > old computer find and open it but if i try to login and browse using beth it says failed to mount window share
